Function Documentation

Null_iterator()

template<class T >

std::vector< T >::const_iterator const & Null_iterator

(

T

)

An iterator that is supposed to point to "nothing" of specified type ;).

Since an iterator can never point to nothing (it can never be null - like a raw pointer), this function "emulates" such a case.
It provides an iterator to a vector that contains nothing, that is, to some empty vector of type T .

Template Parameters

T	- the type parameter.

Returns

std::vector<T>::const_iterator const& - the iterator returned by the begin() function of the empty vector<T>.
